BACKGROUND AND OBJECTIVES The present work was carried out to investigate the ability of Spirulina platensis to produce antimicrobial substance against bacteria and fungi. MATERIALS AND METHODS The cells of the cyanobacterium were subjected to different extractions and the purified antagonistic compound proved to be effective against broad spectrum of bacteria and fungi. The antagonistic comp...

Bile Pigments, Protein Interaction, Conformation, Denaturation The chromophore-protein interactions of C-phycocyanin (C-PC) from Spirulina platensis have been studied by following the partial and complete denaturation with UV-Vis spectroscopy. From comparison with published MO calculations, an elongated conformation of the chromophore is sug­ gested for native C-PC, a cyclic one for denatured C...

In this study, zeolite was employed for the separation and recovery of P from synthetic wastewater and its use as phosphorus (P) source for the cultivation of the green microalga Chlorella vulgaris and the cyanobacterium Arthrospira (Spirulina) platensis. At P-loaded zeolite concentration of 0.15-1 g/L, in which P was limited, the two species displayed quite different behavior regarding their g...

The cyanobacterium Arthrospira is among the most well-known food supplements worldwide known as "Spirulina." While it is a widely recognized health-promoting natural product, there are no reports on the molecular diversity of commercially available brands of "Spirulina" supplements and the occurrence of other cyanobacterial and heterotrophic bacterial microorganisms in these products. In this s...

This study presents the effect of sewage waste water on growth microalga Arthrospira platensis using appropriate standard methods. The results showed that different concentrations affected platensis. A comparison responses treatments revealed there was significant difference (p<0.05) with control (0%) and 5% having highest mean values for when compared other treatments. Among treatments, 30%...
